Abstract: A B S T R A C T     Fluoropolymer containing films are separately formed and applied to substrates to frm novel composites.  The inven-tion process comprises the steps of:    (1) separately forming a uniform film comprising a metered layer of a fluoropolymer containing material; (2) treating the substrate to facilitate film adhesion and bonding; (3) uniformly contacting at least one face of the film with a treated surface of the substrate; and (4) transferring the film material to the treated sub-strate with heat and pressure to obtain a smooth, uniform coated composite.  By a decalcomania technique, the film may be cast in a single or multiple layers on a support member, such as a metal foil, drum or belt, and thereafter the face of the film opposite the support member is uniformly contacted with the substrate and transferred.  The support member is thereafter removed or stripped from the film to expose the laminated composite surface.  Alternatively, the film may be removed from the support member prior to contacting with the substrate.

Abstract: ABSTRACT In the known saw-type tree falling machines the saws turn in a curcular motion.           In my invention the saw blades are hydraulically pulled to the centre of the tree thus cutting on both sides simualtneously in one motion.       (1)  This invention relates to a saw-type tree falling machine. (2)  It is common in tree falling machines for the cutting device to turn in a circular motion thus requiring an extra power source resulting in high manufacturing and maintenance costs. (3)  My invention overcomes the high costs associated with other tree falling saws due to it's simple design and because it operates on the existing hydraulic systems of the carrier machine. (4)  In the drawings Figures 1 through 8 illustrate the various parts comprising the saw-type tree falling machine . Figure 1 is a top  view of the machine with the cutting devices in the open position.  Left said top  plate removed.           Figure 2 shows a top view of the machine with the cutting devices in the closed position.        Figure 3 shows the top and end view of the female guiding blade.   Figure 4 shows the top  view of the right side cutting device.           Figure 5 is the end view of ?  of the frame, the guiding blade, cutting device and the top plate bolted together.           Figure 6 shows the top view of the frame.           Figure 7 shows the top end side view of the cutting teeth. Figure 8 shows the top view of the top right plate.           (5)  In my invention the falling maching is mounted to the carrier machine, by the U-Shaped frame shown in part #1 figures 1 and 2 and separately in figure 6. The female guiding plates Figure 1 and Figure 2, parts #2 are bolted, one on each side of the U-Frame. The top and end views of the right side female guide is shown separately in figure 3 part #2.  The guiding groove is shown by #10. The left side guide is a mirror reflection of the right side guide. The right side cutting device is shown separately in Figure 4 part #3. Part #8 in Figure 4 is the male guiding bar. Part #9 in Figure 4 is the hydraulic cyclinder mounting pin. Part #5 in Figure 4 are the cutting teeth also shown separately in Figure 7, Part #5.

The mounting (1) is attached to one panel and a tension bolt (10), which engages the tension part (3), is attached to the other panel.  Recess (2) is provided at its one face (4) with a supporting surface (5) for the purpose of sup-porting the tension part (3) in the mounting (1).  In order to enable the mounting (1) to be manufactured simply and the ten-sion part (3) to be inserted easily into the mounting (1), the other face (13) of the recess (2) is fashioned to be open and has only a nose (14), which rises inwardly above the tension part (3).  The tension part (3), in turn, is provided with a longitudinal slot (15) which corresponds to the dimensions of the nose (14). In order to insert it in mounting (1), tension part (3) is twisted so that the nose (14) and the longitudinal slot (15) are aligned.  Tension part (3) is then merely pushed into the mounting (1).  By means of a subsequent twisting of the mounting (3), the latter is secured in the axial direction.
